A rotatable hand tool, especially a screwdriver or other rotating tool for screws or nuts. The tool is of the kind having cavities in its handle for storing at least one, or usually several tool bits, which can optionally be attached to a holder attached to and turned by the holder. Such bits can, for example, constitute screwdriver tips, hexagonal socket keys and hexagonal sockets. The handle consists of two main parts, of which one is rotatably enclosed in the other and has cavities arranged in the form of recesses in its periphery, these recesses being accessible by turning the enclosed part so that one of its recesses coincides with an opening in the other part. A limited axial movement between both handle parts and between coacting locking means thereon enables these parts to turn respective to each other in an outer axial position, and is locking them against rotation in an inner axial position of the enclosed part.
